erly alinedposition against the door 3 its end-portion 11 whichis entirely incased extends beyond the door-edge 12 and overlaps the door-frame 5 and the keeper 4. Within the extending end-portion 11 is contained a pan of cylindr cal bolts-13 which are connected by brackets 14 to a post 15. Said cylindrical bolts are disposed vertically I and jconvexedly formed to follow the configuration of-the bolts.- .11 frame or plate 16 form 'ing part of thepost 15 extends therefrom into the interior of the casing 1. Said frame is provided with a groove 17 fitting "over a vertical'tr'ack 18 cast upon the wall of 'casing 1, and the connecting post 15 is fitted slidably'betw'een guiding ledges 19 cast upon the cas'ing-wall, whereby the bolts 13 together with the post 15 an d'frame 16 are thusguided: at all sides against lateral displacement and they may be therefore shiftt 'ed in a vertical direction upwardly and downwardly, from the position shown in Fig. 1 to that shown in Fig. 3 and I Upon the frame 16 is plvoted a 'tumblerpawl 20 at 21 from-where it extends verti-' tained in their elevated state shown in Fig.

1. A lever 28 fulcrumed at 29 upon frame 16 has a pin 30 at the extremity of its arm 31 passing intota slot 32 formed in pawl 20 adjacent its ledge 26 and extending obliquely therefrom. The other arm '33 of said lever extends upwardly fromfulcrum 29 and has its end-portion 34 bent right angularly and its extremity provided with a beveled head 35 that projects outside of the casing. -Pressing upon the head 35 toward the left, as x viewed in thedrawing, rocks the lever 28 andcauses its pin 30to engage the pawl 20 and swing it toward the right about pivot 21,

thereby releasing the locking-ledge 26 from .the lug 27 and rendering the bolts 13 and the parts dependent therewith free to more downwardly. And being thus released the bolts are caused to descend automatically to the position shown in Fig. 3 by means of a spring 36 having one end thereof secured to the frame 16 and its opposite end to the rim of easing 1. When the'bolts 13 are dis posed in their lowered position the upper edge of ledge 26 is retained against the lower edge of lug 27 whereby the bolts are main;

tained locked in. the downward position.

A plate 37 is secured to the shank of knob 10 and is provided with opposite arms 38 that are normally maintained in vertical disposition, as shown, by means of opposite springs 39, secured'to pins 40 upon casing 1, pressing against opposite projections 41 formed on said plate. By this means, also, a semicircular snap movement may be imparted to the arms 38 in the direction of the arrow, Fig. 1, upon turning of the knob 10 half a revolution, said springs automatically alining said arms in vertical dispositionat each half turn of the knob. In order to restore the bolts 13 to their elevated position, the knob 10 is turned for half a revolution and imparts its movement ,to the arms- 38. The lower one of said arms is thereby caused to enter between the ledge 22 and another ledge 42 formed on frame 16, and

' while progressing on its Stroke the arm comprising legs 47, 48" which are fitted and to abut against the lug 27 for maintaining said bolts in elevated position, and the lever 28 is restored to its previous disposition. An arm 44 fixed to a bar 45 secured to the barrel'S serves-for raising the bolts 13 to elevated position by turning of the key 9. Turning of the knob 10 or the key 9 thus raises the bolts to locked elevated position,- and pressing of the lever-head 35 into the casing 1 automatically lowers the bolts to locked lowered position. v

The keeper 4, preferably made of castmetal, is provided with an angle portion 46 against the door-frame 5 and firmly secured thereto by the screws 6. When the keeper 4 is-properly fitted in position its leg 47 is fitted into a recess 47 in the inner side of the door-frame 5 and the leg 48 thereof is fitted into a recess 49 formed in the edge 50 of said frame, so that the outer surfaces of said legs are flush with the surfaces'of the frame 5. A pair of ears 5.1 having central openings 52 and constituting the staple poi t1ons of the keeper 4 are formed ppon the Said ears I keeper-leg 47 adjacent the leg 13. have their openings 52 concentric with each other, and the diameters of said .openings are adaptable to fittingly receive gtllc bolts 13 Upon closing of the door 3 both of the ears 51 enter into the end-portion 11 of the loclocasing 1 through notched openings 53 provided in the side 11 of said end-portion adjacent said door, which notched openings may, as here shown, extend around the remaining sides 11, 11 of the end-portion 11. And when securing the keeper 4 in proper position in the installation of the lock its cars 51 are alined in such manner that when entering the receiving openings 53 in casing 1 the centers'of the ear openings 52 will register with the joint axes of the bolts 13, whereby upon said bolts being immediately thereafter shifted downwardly they will enter into the openings 52 as shown in Fig.

Turning of the knob10 or key 9 to dispose the bolts 13 in the elevated position shown in Fig. 1 causes the door 3 to be maintained in unlocked state so that it may be freely opened or closed; and when it is desired to lock the door it is first closed, and thereupon the upper ear 51 strikes the beveled head 35 of lever 28 and presses it within the casing 1, thereby momentarily causing the bolts 13 to descend into the earopenings 52 in the position shown in Fig. 3.

It will be noted that when one of the arms 38 or the arm 44 is turned to raise the bolts for unlocking the door while it is in closed position, said bolts would tend to immediately drop back into locking engagement within the ear-openings 52, for the reason that the upper ear 51 still continues to 're-' tain the lever-head 35 within the'casing 1, Fig. 2. In order to avoid this objection a detent 54 is pivoted upon the frame 16 and has one end 55 thereof lodged within a notch 56 provided in projection 43 of'pawl 20, so that while the lever-head 35 is retained within the casing by the keeper-ear 51 and the pawl 20 is consequently disposed in swung position toward the right the other end 57 of detent 54 is caused by said pawl to be disposed in the path ofthe arm 38 or 44, as indicated by the dash and dot lines. Said arm being thereby arrested and prevented from completing its stroke it binds against the projection 42 of frame 16 and in this manner retains the bolts 13 in raised unlocked position during the time that the V keeper-ear continues to press against the head 35.. moved away from the keeper the lever-head 35 projects itself fully outward andat once permits the pawl 20 to dispose the detent 54 in the position shown to releasethe arm-38 or 44 for completing its stroke. Upon the door being closed again the keeper actuates And when the door is opened and and frustrate such' attempt. Should it be the lever-head to momentarily cause the lockingmechanismto automatically shift thebolts downwardly into locking engagement with the ears 51.

In their unlocked state'the bolts 13 are entirely concealed and incased, Fig. 1, by

the extending end-portion 11 of the casing 1,

and when said bolts are interlocked with the attempted to bend away or dislocate the keepenears 51 or the bolts 13 laterally the same would be prevented on account, of the projection of the upper and lower bolt extremities 59 within the casing-end 11 and of their incasement thereby. Theinterlocking of the casing-end 11, the keeper-ears 51, and

the bolts 13 will prevent any attempted up and down dislocation of the lock or keeper. The keeper-legs 47, 18 secured to the inner side and edgejof the door-frame 5 will also conduce toward the prevention of attempted dislocation of the keeper or reaching to the bolts 13 through the outer side ofthe door.

It will be evident that by means of this lock construction any other means of picking or dislocation of the look by jimmying will be prevented and burglarizing' or breaking in frustrated.

The automatic interlocking of the bolts 13 with the keeper-ears 51 upon closingof the door adds greatly to the convenience, safety,

and general utility of the'lock.

Variations may be resorted to within the scope of the invention. 1 y
